Title: Learning machine
IPC: G06N3/063
Filed: 1968-12-11
Abstract: 1,255,614. Learning machines. MATSUSHITA ELECTRIC INDUSTRIAL CO. Ltd. 11 Dec., 1968 [18 Dec., 1967; 15 Oct., 1968; 20 Nov., 1968], No. 69023/68. Heading G4R. A learning machine comprises a plurality of weight elements respectively associated with a plurality of input terminals, decision means for comparing the sum of the outputs from the weight elements with a threshold value, means for delivering an error signal representing error between the output signal of said decision means and a predetermined desired output, a learning pulse generator for generating at least one learning pulse in response to said error signal, and control switch circuit means for controlling the supply of the learning pulse to the weight elements to vary the weights of the weight elements electronically until the error signal is reduced to zero. In a first embodiment, the control switch circuit means supplies each learning pulse to each weight element associated with an input terminal carrying a 1 signal, to increment a ring counter in the weight element, the ring counter enabling one of a plurality of transistors to pass a respective weighting voltage to a junction, from which it is passed to the summing circuit by a further transistor enabled by a 1 at the input terminal. The learning pulses are also counted to adjust the threshold if the error signal is not reduced to zero after a certain number of learning pulses. In another embodiment, the error signal, if non-zero, can have either polarity. As long as the error signal is non-zero, pulses are produced, each of which increments a ring counter which selects one of the inputs at a time. If the input signal is 1, a learning pulse is generated in response to this pulse and routed under control of the ring counter to the corresponding weight element which is adjusted up or down according to the polarity of the error signal (supplied to the learning pulse generator. The threshold is controlled by a multistable circuit driven by an AND gate enabled when all the input signals to the learning machine are 1 and any of the pulses produced in response to a non-zero error signal are present. A third embodiment supplies one or four learning pulses at a time (to increase or decrease the weights respectively), when the decision means output and desired output are unequal, depending on which is 1 and which 0. A fourth embodiment is a minor variation of the first.

Abstract: 1,244,799. Pneumatic conveyers; feeding webs. A. MEYER. 5 Dec., 1969 [7 Dec., 1968], No. 59403/69. Headings B8A and B8R. [Also in Division F4] Apparatus for continuously drying material in web form comprises a perforate stationary drum 2 which supports the material. The material 34 is fed to the drum by rollers 30 and progresses over the drum surface in waves 35 induced by gas jets 23 mounted on a rotatable hollow shaft 5. A blower 16 generates a gas pressure in the shaft 15 and hence supplies over to the gas jets. The suction side of the blower is connected to the space between hollow shaft 5 and perforate drum 2 so that the material is held against the drum except at points above the gas jets 13. As the shaft 5 and gas jets 13 are rotated the waves 35 progress across the surface of the drum. Air from the blower is heated by radiators 19, 20 passes through ducts 21, 22, through jet 23 on to the material. The air flow is controlled by shuttered apertures 27 and 29 and flaps 24. The aperture size in the drum 2 may be varied by an apertured band (36), Fig. 3 (not shown), which covers the apertured part of the drum and can be moved relative to it so that the holes in the bank and drum come into or more out of alignment. A number of such bands may be used to cover the drum. In an alternative embodiment, the drum is replaced by a flat plate and the hollow shaft by an endless band carrying the gas jets.

As shown, a uniform positive charge is first applied to a web 4 on being passed in one direction between a uniformly exposed photo-conductive plate 2 and a roller 3 to which a negative potential is applied. Web 4 is then passed in the opposite direction while plate 2 is exposed to a positive light image and a positive potential is applied to roller 3, a positive charge image (corresponding to the non-light struck areas of plate 2) thereby being produced. Web 4 is finally passed in the original direction while plate 2 is exposed to a negative light image and a negative potential is applied to roller 3, a corresponding positive image (corresponding to the light struck areas of plate 2) thereby being produced. The roller may be urged against the photo-conductive plate by means of a coiled spring 8.

Tubes are formed upon a mandrel covered with an elastically compressible layer by applying a solvent resistant inner layer in the form of a foil of polyamide, halogen-substituted hydrocarbon or other plastics material, followed by an additional layer or layers including one of natural or synthetic rubber, and then the unvulcanized tube blank is removed for further processing, damage to the blank being prevented by the elastically compressible layer, which is retained on the mandrel. In a preferred embodiment the elastically compressible layer comprises a braided stocking made from expandible circular fabric, tied down by cords at both ends of the mandrel. The tube blank comprises a seamless polyamide foil tube, produced by injection moulding or extrusion, an intermediate rubber layer, and an outer reinforcing fabric layer. The unvulcanized tube is slid off the covered mandrel and cut into sections which are placed over curved mandrels and then vulcanized to form pipe bends and elbows.
